Abstract
The invention relates to a device for positioning a biological sample analysis plate on an observation device comprising an observation lens and a chassis having a plate support assembly [20]. This assembly comprises a first frame [21] and a second frame [22] able to slide in a plane perpendicular to the observation axis, assumed to be vertical, with the first and second frames each able to move in a direction perpendicular to the direction of movement of the other frame; and a third frame [23] supported by the second frame [22] by means [30] used to maintain said third frame in a plane perpendicular to the observation axis, while leaving the movement free in a vertical plane.
Claims12
A device for positioning a plate [2] comprising one or more samples on an observation or analysis device comprising an observation or analysis lens [3] of at least part of a sample along an observation axis from an observation face [2b] of the plate [2] and a chassis [11] having a support assembly [20]for the plate [2], wherein this support assembly [20] comprises:
- a first movable frame [21] sliding in a plane perpendicular to the observation axis;
- a second movable frame [22] supported by the first frame [21] sliding in said plane perpendicular to the observation axis, the first and second frames [21 and 22] being movable in a direction perpendicular to the direction in which other frame moves,
- a third frame [23] supported by the second frame [22] by means [30] used to maintain the third frame [23] blocked in the plane perpendicular to the observation axis, while leaving the third frame [23] free to move essentially along the observation axis, said third frame [23] presenting means [31 and 33] to immobilise the plate [2], and
- means [40] for ensuring a constant distance between the lens [3] and the observation face [2b] of the plate [2].
A sample observation or analysis device, wherein it comprises a positioning device for a plate [2], said positioning device comprising one or more samples on an observation or analysis device comprising an observation or analysis lens [3] of at least part of a sample along an observation axis from an observation face [2b] of the plate [2] and a chassis [11] having a support assembly [20] for the plate [2], wherein this support assembly [20] comprises:
- a first movable frame [21] sliding in a plane perpendicular to the observation axis;
- a second movable frame [22] supported by the first frame [21] sliding in said plane perpendicular to the observation axis, the first and second frames [21 and 22] being movable in a direction perpendicular to the direction in which other frame moves,
- a third frame [23] supported by the second frame [22] by means [30] used to maintain the third frame [23] blocked in the plane perpendicular to the observation axis, while leaving the third frame [23] free to move essentially along the observation axis, said third frame [23] presenting means [31 and 33] to immobilise the plate [2],- means [40] for ensuring a constant distance between the lens [3] and the observation face [2b]of the plate [2].and
- the sample observation or analysis device further comprises a light source for at least part of a sample and image acquisition means.
